Yes, pics please. Why the dimensional lumber repairs and hangers? Why not proper timberframing repair(or re-engineering stronger)? If you need to get some new or reclaimed timber beams or joists in there, not too hard to find. Not at your local big box stores granted, but there are plenty of barns coming down locally, you can probably find something locally or order some at good prices if you know where to look. Do you have TF experience? Not too hard to learn techniques.
